SPF, which stands for Sender Policy Framework, is an email safety system, which is employed to validate whether an email message is sent by an official server. Using SPF protection for a given domain will prevent the forging of email addresses created with the domain. In layman's terms: enabling this feature for a domain name generates a specific record in the Domain Name System (DNS) containing the IP of the servers that are permitted to send email messages from mail boxes using the domain. Once this record propagates worldwide, it will exist on all of the DNS servers that route the Internet traffic. Whenever a new e-mail message is sent, the initial DNS server it goes through tests whether it comes from an authorized server. When it does, it is sent to the destination address, however when it doesn't originate from a server part of the SPF record for the particular domain, it is discarded. Thus nobody will be able to mask an e-mail address then make it appear as if you are distributing spam messages. This approach is also known as email spoofing.
SPF Protection in Shared Hosting
You can enable the SPF protection option for your domain names with only a couple of clicks in the Hepsia Control Panel, which is provided with all of our Linux shared hosting. This is done from the section bearing the same name and you can allow the protection for any domain name on our exceptional cloud hosting platform. Using a really simple interface, all you will have to submit is the hostname of the mail server which will be authorized to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Of course, you'll be able to include several servers as well, when needed. If your e-mail addresses are managed on our end, you may also take advantage of a more risk-free option by setting a restriction that messages can be sent only when your domains feature our MX records. This alternative can't be used if your web site is here, and your e-mail addresses are with a third-party service provider. In either case, the SPF protection option will strongly enhance your online safety and prevent others from spoofing your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
When you have a semi-dedicated server account from our company, you are able to protect your email addresses by activating the SPF protection service for every domain name hosted in the account with just a few mouse-clicks. This is done in the Emails section of our Hepsia Control Panel that is included with the semi-dedicated accounts and even if you have no previous practical experience with these issues, you will not have any kind of trouble to enable the security. Everything that you'll need to do is to pick a domain name from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your e-mail addresses will be sent globally only if they are sent from that particular server. In case your emails are managed by us and not by a third-party supplier, you'll also be able to take advantage of an option for email messages to be sent only when the domain has our MX records and this would be the most secure option. If you have any questions regarding thisfunction, you will be able to get in touch with our support crew 24/7.
